An alpha particle (m = 6.68e-27 kilogram, q = 3.20e-19 C) is moving perpendicularly to a uniform magnetic field at a speed of 7.88e6 meter per second. Because of the force exerted on it by the magnetic field, it is accelerating at 5.67e12 m/s2. Determine what is the strength of the magnetic field?
An 84.4 kg man is standing at the rear of a 425 kg iceboatthat is moving at 4.16 m/s across the ice that may be considered tobe frictionless. How far did the boat move across the ice while he waswalking
